Shooting outside US NSA headquarters, one hurt

District of Columbia: A shooting erupted Wednesday outside the suburban Washington headquarters of the National Security Agency, a secretive intelligence organisation responsible for global US electronic eavesdropping, leaving at least one person injured, officials said.

NBC News aired aerial images of what appeared to be police surrounding a man on the ground in handcuffs outside the NSA facility in Fort Meade, Maryland.

A black SUV appeared to have crashed into a concrete barrier surrounding the site, and bullet holes were visible in the vehicle`s front windows.

“We can confirm there has been one person injured and we don`t know how the injuries occurred,” an NSA spokesman told AFP.

The local ABC affiliate put the number of injured at three and said a suspect was arrested.

The NSA said the situation was under control, advising motorists that a highway leading to the complex was closed in both direction “due to a police investigation.”
